Applications are open this Trinity term for four internship programmes available to undergraduate and postgraduate Oxford students, offering a range of opportunities to suit different interests and circumstances.
If you are curious about using your maths outside academia, want to learn new skills, or just want a change of pace from your PhD, then consider a policy internship. During a three-month UKRI policy internship at the Joint Nature Conservation Committee, I worked on assessing the impact of human-made underwater noise on harbour porpoises. I got to see what it was like to work for a government advisory body, and how scientific modelling is used to inform policy and real-world decision making, all whilst occasionally spotting dolphins from my office window. In this talk, I will describe my project and use it as a starting point to discuss internships more broadly: what you can gain from them, how they differ from academic research, and how to apply.
Take a break at the end of term with some Mathematrix crafts and sweet treats! Supplies for watercolor and origami will be provided, and you are welcome to bring your own crafts.
Everyone is invited to celebrate International Women in Mathematics Day with a pizza lunch! We will be watching ‘Journeys of Women in Mathematics’, a powerful 20-minute film by the International Mathematical Union showcasing the experiences of women mathematicians worldwide. It follows three mathematicians from India, Cameroon, and Brazil from their home institutions to the (WM)² international meeting, showing their research and what it’s like to be part of the global maths community.
In 1982, Conway introduced the angel-devil game, which is played on an infinite chess board. For fixed k, the angel moves at most distance k from its current position on its turn. The devil then blocks a square permanently. The devil wins if the angel eventually has no legal moves left. Berlekamp showed the devil wins against the 1-angel. Conway asked whether there exists k such that the k-angel has a winning strategy against the devil. This was resolved independently by Kloster, Máthé, and Bowditch in 2006. Bowditch proposed playing the game on Cayley graphs of finitely generated groups. A group for which the devil beats the k-angel for every k is called diabolical. We will explore the ends of these diabolical groups.
